1, I suggest you do gastroscopy, because gastroscopy is more intuitive and clear than barium meal. If you are afraid, you can do a painless gastroscope. Now all hospitals with gastroscopes have basically carried out painless gastroscopy. 2, barium meal, if you really don't want to do a gastroscope, then do a barium meal, but not as clear as a gastroscope. 3. Capsule gastroscopy is only available in the top three hospitals in the province or the affiliated hospitals of medical universities, but not in many provinces and cities, because the price is relatively expensive, mainly because the cost for patients to do this examination is relatively high.
